因此，我已尽一切可能来解决这个错误，这也是我巨大的挫败感。

from sklearn.linear_model import SGDClassifier

train_labels_9 = [(label == 9) for label in train_labels_9]
test_labels_9 = [(label == 9) for label in test_labels_9]

sgd = SGDClassifier(max_iter = 1000, tol = 1e-3)
sgd.fit(train_images,train_labels_9)

below is the error
